Ummm... all you have to do to fool the auto-superscript is place a space between the number and the "th" - which shows up frequently in these documents. And it is very simple to use a lowercase "L" as a number 1 - that is just an asinine statement. Gotta love these "experts" - I hope they are independently wealthy, because their reputations just went down the toilet...
You mean, like this?
111th (all "1"s; in Times New Roman)
1l1th (Middle "1" replaced with a "l"; also in Times New Roman)
I can just see my dad doing that when he had staff duty......NOT!!!!
He would have picked up the typewriter....driven to Benning....gone up the 34 foot tower.....sling loaded the typewriter to the slide line......and laughed as his went down the line and smashed into the end of the line.
